Fastening nuts 17, of any suitableform, are

applied to the exteriorly projecting threaded ends 14 of the bolt rods, to holdthe parts assembled together as above described.

Arranged to project laterally from the outer side ofeach innerpanel 10 are com- 1 bined suspension and spacing struts for attachment to the wall structure of interior finishing or facing panels 18; which panels are of dimensions corresponding to those of the panels 10 11, and which may be made of any suitable interior finishing. material, such as pressed wood, plaster board or other forms of interior wall board material, or'in factany panel material suitable for. thepurs pose. Said combined suspension and spacing struts' preferably comprise sheetlmetal members 19' formed at theirinner ends with anangular base flange 20gto-abut theouter surface of the inner panel 10, and at their outer ends with an upstanding angular tongue 21 for purposes to be subsequently disclosed- Said base flanges 20 are provided with openings through which saidbolt rods 12 may pass, whereby the latterv may be utilized to anchor the-suspension and spacing struts in operative assembled relation to the wall structure; For example, said base flanges 20 are disposed to lie between the head; portions 13,0f the bolt rods and the panels 10, so that when the boltrods are drawn tight the same serve to :hold the base flanges 20 anchored to the panels 10;, In order, to prevent twisting or like .displacement of the struts from operative. assembled J relation to the wall structure, the freecorners of'said base flanges 20 are preferably formed to provide spurs or prongs 22" which penetrate the material of the panel 10.i.-'.It

' will be obvious that any other means of hold-t ing connection may be established between theboltrods 12 and the base flanges 20 of the struts, as e. g.. threading the formerinto the latter, i nstead of utilizing the keeper head portion 13 above mentioned. The interior. finishing or facing panels 18areprovided on their inner sides, with metallic. or like socket strops 23 toreceive the tongues 21 m of the struts, whereby the panels 18 are supported andspaced by the latter inoperative assembled relationto the panel 10 and Y plete wall ing units prior to-the erection thereof, or during the erection thereof, or after the oompletion of the whole wall structure, as may 7 be most convenient in any givencase.

The wall form building units are provided with means to mutually interlock the same together when a plurality thereof are assembled edge tohedge in the process of erecting the same and for forming the com "structure. The interlocking means comprises female receiving channels formedalong one horizontal and one vertical marginv of each panel '10, 11 and 1 8 of each wall form building unit, so as to; receive free marginal portions of adjacent corresponding panels of abutting wall form building units,jas such units are successively assembled and built up in adjoined- .wall forming relation. Preferably-these female receiving channels are formed as follows:-

Secured to-theinner and outer sides respectively of the inner panel 10 are marginal strips2i-24' "to project beyond ahorizontal edge, such as the top edge, and beyond a vertical edge,sucl1 as the left hand edge, thereof. These strips 2 may be made of the same material as the panelor of any other suitable material,and the strips may be secured to the panel by nailing or by any other suitable fasteningmethodiormeans, The strips 2424 form femalereceiving channels closed on' both sides and'contiguous to the. panel edges bordered thereby.- Secured in like manner to the outer side of panel 11 are marginal strips'25 to project beyond a corresponding horizontal edge and a corresponding vertical edge thereof, thus providing receiving chana the inner side and contiguous to thepanel edges bordered by saidstrips 26.

In the method of producing a building wall 3 structure according tothis invention, a suitable foundation,- as 27, is prepared upon which aylower-course of assembled wall form building units is erected.- Said first course of units are, assembled one with another by a engaging free vertical edgesof the panels of one i-unit with channeled margins, of next adacent,.abutt1ng:un1ts, whereby said'units are interlocked one with another, andwith their channeled horizontalmargins upward.

The lower marginal portions; of'the panels 11 and 18 of the first course of thus erected 4 units are @cutaway to provide suitably spaced notches 28 to receive-and straddle first floor ams? 2 ,;which are supported by andupon,
